See Article 16 - Freedom to conduct a business - http://fra.europa.eu/en/eu-charter/article/16-freedom-conduc... and the article The 16th of all EU-r rights: the right to conduct a business and how the Charter contributes - https://www.eurac.edu/en/blogs/eureka/the-16th-of-all-eu-r-r... - for the European perspective of it.
Right. By stepping farther from the open market and killing some personal freedom. (Also, word "democratically" is absolutely meaningless in this context, but that's the usual mode it is used in in western politics.)
No, it isn't. When a law / regulation / policy is made all stakeholders are consulted and their views sought on it. Consumers are one of the stakeholders in context of what we are talking about. Politicians than work out a compromise that balances everyone's concerns. That's basically democracy at work.
No, we are democratically balancing consumer rights with the rights of entrepreneurs to make money. Consumers need the right to repair and not be limited with closed, proprietary standards. That entrepreneurs may take take a slight hit on their profit due to this is acceptable as protecting the consumer enhances the well being of the overall society that both entrepreneurs and the consumers are part of. (And note that right to repair and open standards can also foster more competition in the "free market" and reduce monopolistic abuses - so it is really a win-win for both sides).
